Beneficial effect of fluid warming in elderly patients with bladder cancer undergoing Da Vinci robotic-assisted laparoscopic radical cystectomy.	OBJECTIVES: The enhanced recovery after surgery (ERAS) protocol recommends prevention of intraoperative hypothermia. However, the beneficial effect of maintaining normothermia after radical cystectomy has not been evaluated. This study aimed to investigate the efficacy of fluid warming nursing in elderly patients undergoing Da Vinci robotic-assisted laparoscopic radical cystectomy. METHODS: A total of 108 patients with bladder cancer scheduled to undergo DaVinci robotic-assisted laparoscopic radical cystectomy were recruited and randomly divided into the control group (n=55), which received a warming blanket (43°C) during the intraoperative period and the warming group (n=53), in which all intraoperative fluids were administered via a fluid warmer (41°C). The surgical data, body temperature, coagulation function indexes, and postoperative complications were compared between the two groups. RESULTS: Compared to the control group, the warming group had significantly less intraoperative transfusion (p=0.028) and shorter hospitalization days (p<0.05). During the entire intraoperative period (from 1 to 6h), body temperature was significantly higher in the warming group than in the control group. There were significant differences in preoperative fibrinogen level, white blood cell count, total bilirubin level, intraoperative lactose level, postoperative thrombin time (TT), and platelet count between the control and warming groups. Multivariate linear regression analysis demonstrated that TT was the only significant factor, suggesting that the warming group had a lower TT than the control group. CONCLUSION: Fluid warming nursing can effectively reduce transfusion requirement and hospitalization days, maintain intraoperative normothermia, and promote postoperative coagulation function in elderly patients undergoing Da Vinci robotic-assisted laparoscopic radical cystectomy.	bladder
Impact of body size and body composition on bladder cancer outcomes: Risk stratification and opportunity for novel interventions.	Body size is emerging as a novel and clinically-relevant patient factor in bladder cancer research. Historically, a patient's body mass index (BMI) has been used as a proxy for obesity but it shows inconsistent associations with risk of developing the disease as well as with most clinical outcomes. More specific body composition features can be derived for patients using a variety of methods. To date, skeletal muscle measurements derived from preoperative computed tomography scans have shown the most consistent associations with clinical outcomes. Importantly, skeletal muscle can potentially be modified through resistance training and/or nutritional interventions. Large scale studies that evaluate the prognostic impact of not only body composition features at baseline but also describe changes in body composition post-treatment are needed to move the field forward to ultimately improve clinical outcomes for bladder cancer patients.	bladder
Small Cell Carcinoma of Bladder; Still A Diagnostic and Therapeutic Challenge: Seven Years of Experience and Follow-up in A Referral Center.	PURPOSE: To report clinical, histopathological, and treatment features of small cell carcinoma of (SmccB) bladder during 7 years in a referral center. METHODS: The clinical, histopathological features, treatment modalities, and outcome of all patients with bladder SmccB treated between 2009 and 2016 who were managed in Hasheminejad Kidney Center (HKC) were retrospectively collected. RESULTS: Thirteen patients were diagnosed and managed with SmccB. The average age of patients was 64.92 years. For each patient, 8 markers were used for IHC staining on average. Neuroendocrine markers such as CD 56, Neuron Specific Enolase, Synaptophysin, and Chromogranin were found in a significant percentage of patients (69%, 38%, 54%, and 31% respectively). Patients were managed with TURBT alone (N=3), chemotherapy after TURBT (N=4), chemotherapy plus radical surgery (N=4) and radical surgery alone (N=2). The best clinical result was seen in chemotherapy received patients with or without radical surgery. The mean(SE) of survival rate in patients who received only chemotherapy alone was 42.4 (10.0) months, while in those who were managed with chemotherapy plus radical surgery it was 47.7 (10.1) months. CONCLUSION: In our center immunohistochemistry was needed for definitive diagnosis in 17/19 samples. Misdiagnosis happened in two samples without IHC request. We think that use of immunohistochemistry should be mandatory for diagnosis of SmccB to exclude misdiagnosis. Chemotherapy is the most important part of treatment and the addition of radical surgery can slightly improve patients' survival.	bladder
A comparative propensity score-matched analysis of perioperative outcomes of intracorporeal vs extracorporeal urinary diversion after robot-assisted radical cystectomy: results from the International Robotic Cystectomy Consortium.	OBJECTIVE: To compare the perioperative outcomes of intracorporeal (ICUD) vs extracorporeal urinary diversion (ECUD) after robot-assisted radical cystectomy (RARC). PATIENTS AND METHODS: We retrospectively reviewed the prospectively maintained International Robotic Cystectomy Consortium (IRCC) database. A total of 972 patients from 28 institutions who underwent RARC were included. Propensity score matching was used to match patients based on age, gender, body mass index (BMI), American Society of Anesthesiologists Score (ASA) score, Charlson Comorbidity Index (CCI) score, prior radiation and abdominal surgery, receipt of neoadjuvant chemotherapy, and clinical staging. Matched cohorts were compared. Multivariate stepwise logistic and linear regression models were fit to evaluate variables associated with receiving ICUD, operating time, 90-day high-grade complications (Clavien-Dindo Classification Grade ≥III), and 90-day readmissions after RARC. RESULTS: Utilisation of ICUD increased from 0% in 2005 to 95% in 2018. The ICUD patients had more overall complications (66% vs 58%, P = 0.01) and readmissions (27% vs 17%, P = 0.01), but not high-grade complications (21% vs 24%, P = 0.22). A more recent RC era and ileal conduit diversion were associated with receiving an ICUD. Higher BMI, ASA score ≥3, and receiving a neobladder were associated with longer operating times. Shorter operating time was associated with male gender, older age, ICUD, and centres with a larger annual average RC volume. Longer intensive care unit stay was associated with 90-day high-grade complications. Higher CCI score, prior radiation therapy, neoadjuvant chemotherapy, and ICUD were associated with a higher risk of 90-day readmissions. CONCLUSIONS: Utilisation of ICUD has increased over the past decade. ICUD was associated with more overall complications and readmissions compared to ECUD, but not high-grade complications.	bladder
Health-related quality of life in patients undergoing radical cystectomy with modified single stoma cutaneous ureterostomy, bilateral cutaneous ureterostomy and ileal conduit.	PURPOSE: To compare the clinical outcomes and patients' health-related quality of life (HR-QoL) with modified single stoma cutaneous ureterostomy (MCU), bilateral standard cutaneous ureterostomy (SCU) and ileal conduit (IC) using validated diversion-specific HR-QoL instrument. METHODS: The study included 70 patients who underwent open radical cystectomy with either MCU, SCU, or IC from May 2017 to May 2018. In total 23, 25 and 22 patients were included in each group, respectively, after applying the following exclusion criteria: female, pre- and postoperative radio and chemotherapy, palliative surgery. HR-QoL was evaluated using the European Association of Research and Treatment of Cancer Quality of Life Core Questionnaire (EORTC-QLQ-C30) and Functional Assessment of Cancer Therapy for patients undergoing radical cystectomy (FACT-Bl-Cys). RESULTS: Global health status per EORTC-QLQ-C30 was the only domain that was found to be statistically better in the IC group compared to MCU (p = 0.007). Higher scores in additional concerns (p = 0.008), functional health domains (p = 0.002), satisfaction from urinary diversion (p = 0.004), and total score (p = 0.027) per FACT-Bl-Cys questionnaire, global health status (p < 0.001), and symptom scale (p = 0.017) per EORTC-QLQ-C30 were observed in IC compered to SCU. Patients with MCU had better scores of functional health (p = 0.012), satisfaction from urinary diversion (p = 0.001), and global health status (p = 0.008) than SCU. CONCLUSION: IC is associated with better quality of life scores compared to SCU and similar scores compared to MCU. MCU possesses better scores of HR-QoL domains compared to SCU. Our results suggest that MCU should be preferred in patients requiring SCU and could be considered for patients requiring IC.	bladder
Atypical oncologic failure after laparoscopic and robot-assisted radical cystectomy at a single institution.	BACKGROUND: The incidence of atypical oncologic failure in patients with bladder cancer, including peritoneal carcinomatosis, and recurrences at the port site and soft tissue after laparoscopic and robot-assisted radical cystectomy are not well characterized. METHODS: We retrospectively reviewed the records of 52, 51, and 12 patients who underwent open, laparoscopic, and robot-assisted radical cystectomy, respectively, for bladder cancer from 2007 to 2018 at our institution. We identified techniques associated with atypical oncologic failure. RESULTS: The median follow-up period was 29 months. Among the 115 patients, 29 (25%) experienced oncological recurrences, and 7 (6%), 12 (10%), and 23 (20%) had atypical, local, and distant recurrences, respectively. The laparoscopic and robot-assisted radical cystectomy groups had significantly higher incidences of total atypical oncologic failure than the open radical cystectomy group (p = 0.013), including six, one, and two patients with peritoneal carcinomatosis, port site carcinomatosis, and soft tissue involvement, respectively. All 7 patients with atypical oncologic failure died of cancer; the median time from surgery to death was 9.3 months. All these patients were cT ≧ 3 and had grade 3 disease. In three patients (43%), the pathological tissue contained variants other than urothelial carcinoma. Five (71%) were among the initial twenty patients. Four patients (57%) had histories of intraoperative urine spillage or bladder perforation during transurethral resection. CONCLUSIONS: Patients with cT ≧ 3 stage, with pathological variants other than urothelial carcinoma, and those undergoing procedures that lead to extravesical dissemination should avoid laparoscopic radical cystectomy when the procedures are first introduced.	bladder
Association of NAD (P) H Quinine Oxidoreductase 1 rs1800566 Polymorphism with Bladder and Prostate Cancers - a Systematic Review and Meta-Analysis.	BACKGROUND: Number of studies has been performed to investigate the association of NAD (P) H quinine oxidoreductase 1 (NQO1) rs1800566 polymorphism with risk of bladder and prostate cancers, but presented inconsistent results. Therefore, we performed a meta-analysis to provide a comprehensive data on the association of NQO1 rs1800566 polymorphism with bladder and prostate cancers. METHODS: All eligible studies were identified in PubMed, Google Scholar, EMBASE, and China National Knowledge Infrastructure databases before June 01, 2019. RESULTS: A total of 22 case-control studies including 15 studies with 4,413 cases and 4,275 controls on bladder cancer and 7 studies with 762 cases and 1,813 controls on prostate cancer were selected. Overall, pooled data showed that the NQO1 rs1800566 polymorphism was significantly associated with an increased risk of bladder cancer (T vs. C: OR 1.300; 95% CI 1.112-1.518; P = 0.001; TT vs. CC: OR 1.415; 95% CI 1.084-1.847; P = 0.011; TC vs. CC: OR 1.389; 95% CI 1.111-1.738; P = 0.004; TT + TC vs. CC: OR 1.428; 95% CI 1.145-1.782; P = 0.002) and prostate cancer (TC vs. CC: OR 1.276; 95% CI 1.047-1.555; P = 0.016; TT + TC vs. CC: OR 1.268; 95% CI 1.050-1.532; P = 0.014). The stratified analysis by ethnicity revealed an increased risk of bladder cancer among Caucasians and prostate cancer among Asians. CONCLUSION: This meta-analysis suggested that the NQO1 rs1800566 polymorphism was significantly associated with increased risk of bladder and prostate cancers.	bladder
Biomarkers predicting oncological outcomes of high-risk non-muscle-invasive bladder cancer.	INTRODUCTION: The European Organization for Research and Treatment of Cancer (EORTC) and the Spanish Urological Club for Oncological Treatment (CUETO) scoring systems show limited accuracy for the prediction of disease recurrence and progression of non-muscle-invasive bladder cancer (NMIBC). This aspect is even more relevant in the category of HR NMIBC. Biomarkers might potentially help to further categorize the outcomes of these patients. Therefore, we sought to review the evidence available on tissue-based, urinary, and serum biomarkers for the prediction of recurrence, progression, and survival in HR NMIBC. EVIDENCE ACQUISITION: A systematic literature review without time restrictions was performed using PubMed/EMBASE, Web of Science, SCOPUS, and the Cochrane Libraries. The search was filtered for articles in the English, Italian, German, French, and Spanish languages, involving patients with more than 18 years of age. Relevant papers on tissue-based, serum and urinary biomarkers related to the prediction of oncological outcomes for high-risk bladder cancer patients were included in the analyses. EVIDENCE SYNTHESIS: Overall, 71 studies were eligible for inclusion in this review. The majority of the investigations performed so far focused on immunohistochemical analyses on tumoral tissue. Overall, p53 was the most studied biomarker, but results regarding its prognostic and predictive role were contradictory. Ki67 seems to be a promising biomarker in the prediction of recurrence. Recently, PD-L1 has been associated with the prediction of recurrence free survival and of treatment-refractory disease. Markers developed un urine samples are focused on commercially available kits, which currently do not unequivocally show strongly superior levels of accuracy to cytology. However, they have demonstrated to be potentially helpful in the prediction of recurrence. Blood-based biomarkers represent an emerging reality with promising future applications. CONCLUSIONS: Despite a long history of attempts to discover accurate biomarkers predicting oncological outcomes for HR NMIBC, contradictory or uncertain findings render the adoption of this ancillary techniques in clinical practice still unlikely. Future attempts should be directed to the development of prospective trials and the definition of standardized cut-off levels to render findings worthy of comparison.	bladder
pT1 high-grade bladder cancer: histologic criteria, pitfalls in the assessment of invasion, and substaging.	Most patients with bladder carcinoma are diagnosed with non-muscle-invasive disease, stage Ta, and pT1. Stage remains as the single most important prognostic indicator in urothelial carcinoma. Among the pT1 bladder cancer patients, recurrence and progression of disease occur in 50% and 10%, respectively. The identification of high-risk patients within the pT1 subgroup remains an important clinical goal and an active field of research. Substaging of pT1 disease has been claimed as important histologic discriminator by the 2016 World Health Organization (WHO) classification of the genitourinary tract tumors and by the 8th edition of the American Joint Committee on Cancer (AJCC) staging manual supporting its implementation in clinical practice. Interobserver variation in pT1 diagnosis and the associated pitfalls in pT1 assessment are the critical pathological issues. The aim of this review paper is to provide the practicing pathologist with the state of the art of morphological and immunohistochemical features useful for the diagnosis of early invasive bladder carcinomas, including practical clues on how to avoid relevant interpretative pitfalls, and to summarize the current status of pT1 substaging.	bladder
[Surgery only? Multimodal treatment for urothelial carcinoma of the bladder].	Radical cystectomy is the gold standard in treatment of muscle invasive bladder carcinoma. Especially for patients with advanced tumours, multimodal therapies play an important role in optimising patient care. In older patients with multiple comorbidities, who are not eligible for surgery, alternative treatment modalities are needed as well. This article summarises the current literature on multimodal treatment options in a neoadjuvant and adjuvant setting and analyses alternative potentially curative treatments. The article also summarises the initial results using checkpoint inhibitors in a multimodal treatment setting.	bladder
Automated Detection and Grading of Non-Muscle-Invasive Urothelial Cell Carcinoma of the Bladder.	Accurate grading of non-muscle-invasive urothelial cell carcinoma is of major importance; however, high interobserver variability exists. A fully automated detection and grading network based on deep learning is proposed to enhance reproducibility. A total of 328 transurethral resection specimens from 232 patients were included, and a consensus reading by three specialized pathologists was used. The slides were digitized, and the urothelium was annotated by expert observers. The U-Net-based segmentation network was trained to automatically detect urothelium. This detection was used as input for the classification network. The classification network aimed to grade the tumors according to the World Health Organization grading system adopted in 2004. The automated grading was compared with the consensus and individual grading. The segmentation network resulted in an accurate detection of urothelium. The automated grading shows moderate agreement (κ = 0.48 ± 0.14 SEM) with the consensus reading. The agreement among pathologists ranges between fair (κ = 0.35 ± 0.13 SEM and κ = 0.38 ± 0.11 SEM) and moderate (κ = 0.52 ± 0.13 SEM). The automated classification correctly graded 76% of the low-grade cancers and 71% of the high-grade cancers according to the consensus reading. These results indicate that deep learning can be used for the fully automated detection and grading of urothelial cell carcinoma.	bladder
The role of device-assisted therapies in the management of non-muscle invasive bladder cancer: A systematic review.	"OBJECTIVE: Despite optimal treatment, patients affected by non-muscle invasive bladder cancer (NMIBC) suffer from high risk of recurrence and progression. Intravescical device assisted therapies such as radiofrequency induced thermochemotherapeutic effect (RITE) and electromotive drug administration (EMDA) have shown promising effect in enhancing the effect of intravescical chemotherapies. The aim of the study was to assess clinical outcomes of these two devices in non-muscle invasive bladder cancer. METHODS: A systematic literature review was performed in December 2019 using the Medline, Embase, and Web of Science databases. Only articles published in the last 10 years were considered (2009-2019). The articles were selected using the following keywords association: ""bladder cancer"" AND ""EMDA' AND ""synergo"" AND ""hyperchemotherapy"" AND ""electromotive drug administration"", AND ""radiofrequency induced thermochemotherapeutic"" AND ""RITE"". RESULTS: We found 16 studies published in the last ten years regarding the efficacy of RITE (12 studies) and EMDA (4 studies) in the treatment of NMIBC. Both RITE and EMDA showed promising results in the treatment of intermediate and high risk NMIBC as well as in patients affected by recurrent BCa after BCG failure. In high-risk BCG naïve NMIBC patients treated with EMDA recurrence and progression rates were 68% and 95%, respectively. Considering RITE, recurrence and progression range rates were 43%-88% and 62%-97%, respectively. Discordance results were reported regarding its effect on patients with carcinoma in situ. However, only few studies could be compared since differences exist regarding inclusion criteria with high patients' heterogeneity. Considering recurrence after BCG, recurrence and progression range rates were 29%-29.2% and 62%-83% for RITE and 25% and 75% for EMDA, respectively. CONCLUSION: Delivery of intravescical hyperthermia seems to enhance the normal effect of intravescical chemotherapy instillation. Although prospective trials supported its effect on both BCG naïve and BCG failure patients, data are urgently required to validate these findings and to understand its effect on patients with carcinoma in situ.

Assessment of ex-vivo efficacy (oncogram) of immunotherapeutic and chemotherapeutic agents in bladder cancer: A pilot study of personalized treatment.	PURPOSE: To investigate the ex-vivo efficacy of immunotherapeutics and chemotherapeutics in bladder cancer primary cell cultures, to assess the applicability of the method according to the results and to evaluate suitability of the oncogram method for personalized treatment of bladder cancer. METHODS: After receiving ethics committee approval, tumor tissue was obtained from patients with transurethral resection performed due to bladder tumor from 2015 to 2017. Primary culture was produced from the obtained fresh tissue. Each culture was divided into 6 groups. The control group had only medium applied, while the other groups had Bacillus Calmette Guerin (BCG), Interferon-α (IFN-α), Gemcitabine, BCG+IFN-α and BCG+Gemcitabine, respectively. Viability tests in the 24th hour were performed on each culture. The results of all cases were compared with their own controls. Also, results of each case were compared between the cases with similar pathologic results. RESULTS: The study assessed 24 bladder cancer cases. Mean patient age was 66.2±11.7 years (34-83), with 19 male (79.5%) and 5 female patients (20.5%). When data were compared between the groups, viability percentages were 31.2%, 30.9%, 27.7%, 32.1% and 29.4% in the BCG, IFN-α, Gemcitabine, BCG+IFN-α and BCG+Gemcitabine groups compared with their own controls (73.1%), respectively (p<0.001). In addition, we found that viability results were not similar in all cases. CONCLUSIONS: Cell cultures produced from bladder cancer tissue might help to determine sensitivity to treatment. This ex-vivo method (oncogram) is a simple and applicable method that can be used for personalized treatment before intravesical or systemic therapy.	bladder
